“…However, a survey that selects galaxies only above an isophotal threshold of = 2 4 : 5 , and adopts magnitudes based on a constant isophotal-to-total magnitude correction (m tot = m iso 0:27 assumed here), would recover the luminosity function shown by the solid circles, similar to that observed by Loveday et al (1992). Further details of such simulations can be found in Ferguson & McGaugh (1994). The projected density of galaxies as a function of radius in the Virgo cluster.…”

“…The right panel shows the intrinsic LF and the LF recovered by a eldgalaxy survey similar to that of Loveday et al (1992). The recovered shape is signicantly atter than the intrinsic slope both because many galaxies fall below the isophotal threshold, and because the constant correction from isophotal to total magnitudes systematically underestimates the ux from the galaxies with the lowest surface brightnesses (McGaugh 1994;Ferguson & McGaugh 1994).…”

Dwarf elliptical (dE) galaxies, with blue absolute magnitudes typically fainter than M B = 16, are the most numerous type of galaxy in the nearby universe. Tremendous advances have been made over the past several years in delineating the properties of both Local Group satellite dE's and the large dE populations of nearby clusters. We review some of these advances, with particular attention to how w ell currently available data can constrain (a) models for the formation of dE's, (b) the physical and evolutionary connections between dierent t ypes of galaxies (nucleated and nonnucleated dE's, compact E's, irregulars, and blue compact dwarfs) that overlap in the same portion of the mass-spectrum of galaxies, (c) the contribution of dE's to the galaxy luminosity functions in clusters and the eld, (d) the star-forming histories of dE's and their possible contribution to faint galaxy counts, and (e) the clustering properties of dE's.In addressing these issues, we highlight the extent to which selection eects temper these constraints, and outline areas where new data would be particularly valuable.

“…The only study of patients with Type 1 DM has suggested that the presence of the APO e4 allele was associated with worse cognitive performance, but this was limited to women; no genetic influence on cognition was found among men in the study [11]. Although it is plausible that the presence of an APO e4 allele could exacerbate the neurocognitive consequences of glycaemic insults (severe hypoglycaemia and ⁄ or chronic hyperglycaemia), no interaction between genotype and previous exposure to severe hypoglycaemia was found in that study and interactions with persistent elevations in glycated haemoglobin (HbA 1c ) were not tested.…”

“…Increasing evidence also suggests that the central nervous system (CNS) may be affected adversely by diabetes and its treatment [3,4], but the underlying pathophysiological mechanisms remain poorly understood. Specific polymorphisms of the apolipoprotein E (APOE) and angiotensin-converting enzyme (ACE) genes have been reported to increase the risk for Alzheimer's disease as well as the risk for cognitive dysfunction in the general population and in individuals with Type 2 diabetes [5][6][7][8][9][10], but few studies have explicitly examined whether genetic factors influence risk of cognitive dysfunction in patients with Type 1 DM [11].…”

The associations of apolipoprotein E and angiotensin‐converting enzyme polymorphisms and cognitive function in Type 1 diabetes based on an 18‐year follow‐up of the DCCT cohort

Aims-Specific polymorphisms of the apolipoprotein E (APOE) and angiotensin-converting enzyme (ACE) genes appear to increase risk for Alzheimer's disease and cognitive dysfunction in the general population, yet little research has examined whether genetic factors influence risk of cognitive dysfunction in patients with Type 1 diabetes. The long-term follow-up of the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) population provides an opportunity to examine if specific genetic variations in APOE and ACE alter risk for cognitive decline.Methods-Neurocognitive function in Type 1 diabetic subjects from the DCCT/EDIC study was assessed at DCCT entry and re-assessed approximately 18 years later, using a comprehensive Supporting InformationAdditional Supporting Information may be found in the online version of this article:Please note: Wiley-Blackwell are not responsible for the content or functionality of any supporting materials supplied by the authors.

(HbA 1c ) and the frequency of severe hypoglycaemic events leading to coma or seizures were measured over the 18-year follow-up. We determined whether the APO εs4 and ACE intron 16 indel genotypes were associated with baseline cognitive function and with change over time, and whether they conferred added risk in those subjects experiencing severe hypoglycaemic events or greater glycaemic exposure. NIH Public AccessResults-None of the APOE or ACE polymorphisms were associated with either baseline cognitive performance or change in cognition over the 18-year follow-up. Moreover, none of the genotype variations altered the risk of cognitive dysfunction in those subjects with severe hypoglycaemic episodes or high HbA 1c .Conclusions-In this sample of young and middle-aged adults with Type 1 diabetes, APOε4 and ACED alleles do not appear to increase risk of cognitive dysfunction.

“…[167] Integration of DESI with liquid samples, increased salt tolerance, [160,168] and ionization of only the species of interest, have proven liquid DESI to be an especially attractive route to analyze biological samples, such as proteins. [169][170][171] Investigation and accurate monitoring of post-translational modifications (PTMs) of proteins is especially important for proteomics research, since PTMs are critical to protein function. In traditional spray-based approaches, however, the phosphorylation PTM of proteins has low ionization efficiency due to deprotonation of the phosphate groups.…”

This MiniReview details the evolution and present state of combined electrochemical (EC) and atmospheric pressure sampling/ionization mass spectrometric (MS) techniques, with an emphasis on biologically relevant investigations. Particular attention is paid to how innate EC processes can be exploited to gain additional information about an analyte, and how these effects influence experimental design. A general overview of EC‐MS techniques underscores the complementary nature of the two techniques.
